HARVEY MORY AND SABIIUEL H. BELLAH, OF CAMERON, TEXAS.

Specification forming part of Letters Patent No. 146,839, dated January 27, 1874; application filed September G, 1873.

To all whom it may concern Be it known that we, HARvEY MonEY and SAMUEL H.BELLAH, of Cameron, in the county of Milani a-nd State of Texas, have invented a new and Improved Portable SaWing-Machine, of which the following is a specification:

`The invention will iirst be fully described, and then pointed ont in the claim.

Figurel is a plan view of our improved machine; and Fig. 2 is a sectional elevation of Fig. 1, taken on the line x.

Similar letters of reference indicate correspending parts.

A represents a fra-1ne,1nounted on a truck of, preferably, three low Wheels,B, Withwhich said frame is provided, also horizontal Ways C, for a saw-frame, D, to slide forward and backward in, the saw projecting at one side of the frame, as shown in Fig. 1. Said frame is also provided with vertical Ways D, into which the saw can be shifted when it is desired' to saw felled trees into blocks. This saw-frame has a forked pitman-rod, E, attached to each end, one of which is connected directly to the crank F of the driving-shaft G, and the other is connected to the rock-lever H, which is connected by the rod I to another crank, J, on said shaft, the tvvo cranks being arranged at opposite sides of the axis. The crank-shaft is geared by multiplying Wheels K with the hand crank-shaft L, which has acrank at each endgfor being turned by a ina-n at each. The saW-framehas afeedscrew, M, fitted in aslotted bar, N, with a collar, 0, at each side of said bar, so that it can feed the trame forward and back, While said fra-nie reciprocates to Work the saw. The screw Works in a nut fixed on the frame at P, and gears by along nut,Q, with a counter-shaft, It, and pinion, which is turned by the feed-belt S, Workin g from the crank-shaft G.

When it is desired to arrange the saw vertically for cutting the felled trees up into blocks, the feed-seresr andthe rods E are disconnected, the saw-frame shifted up into the vertical Ways D and again connected to rods E, suitably arran ged for the sawin that position. The crank shaft G and the point of connection, T, with the rock-lever H are arranged as high above the saw-frame when it lies in the horizontal position as can well be and work Well,so`tl 1at they will be high enough to work Well with the saw-frame when it is arranged vertically for cutting oit the felled trunks. To protect the drivin g-gear, we build a box, U, around it, and provide said box with a hinged ,cover to afford access.

Having thus described our invention, we claim as new and desire to secure by Letters Patent- 4 The combination of the two connecting-rods E, rock-lever H, and connecting-rod I with the said saw-frame and double-cranked shaft G, substantially as specified.
